motives someone might have for hitting norway. in other words, it could be some kind of outside plot, possibly linked to al qaeda, etc. right now, if you look at the backs on the ground -- the facts on the ground, there's a one man so far, he is 32, norwegian. he has attacked the central power, but also a political party youth camp on the island. there is the possibility that this is a norwegian domestic extremist. >> does norway have any anti- government extremist groups that you are aware of? >> not that i am aware of. i have posed this question to people and they say no. norwegians will tell you that they have had threats in the past from al qaeda-linked groups.
